So, S1000RR 2017, K46, almost 8k miles, Power commander installed, autotune, full akrapovic, K&N air filter, start map from akrapovic adapted with autotune.
Sometimes, randomly and rarely, 5-10 times in one year, I get a small cut off in low rpm, 2500-4000 mostly, few miliseconds, only in steady throttle, never in power. No ISTA errors.
I presume there is a spark coil guilty. Can I test them and if so, how? If not, I'm thinking to buy one, brand new, aprox 120 USD, and replace them by turn.

Hi, i don't think coming from your spark coil guilty

On my BMW S1000RR 2020, i have exactly same problem and come of my oil BMW change this part 11 11 1 739 907 and work like a charm after that

For my S1000R similary problem, but it's adaptation value bad, just reset on ISTA and perfect after that

I really doubt that oil spraying nozzle is cause... Is more an electrical cause, like loosing a spark from a cylinder. That issue is very rare and for a few miliseconds, like I said, but exist. I could live with it but my OCD won't let me.
Are too much variables involved, power commander, full exhaust... Seeing recalls and numerous coil issues on k67 I've presumed that is most probably cause... I'll try to eliminate PCV and see if this will happen. On the other hand, as I've read, ISTA should show spark coil failure. But isn't like dead dead...

Hi, ok try this and say me if you find problem

Thanks

I think it was bad gas... so sensible after PCV map.
